What is the relationship between temperature and elevation in the different layers of the atmosphere?
The troposphere gets its heat from the ground, and so temperature decreases with altitude. Warm air rises and cool air sinks and so the troposphere is unstable. In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun’s harmful UV.
What is the relationship of altitude and temperature?
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it’s snowing), the temperature decreases more slowly with height.
What type of relationship exists between the altitude and the temperature in the troposphere?
The temperature of the troposphere generally decreases with altitude, although inversions can occur in the planetary boundary layer. And, saturation vapor pressure decreases strongly as temperature drops.
What relationship does this graph show between atmospheric pressure and altitude?
The two have an inverse relationship, that is, when elevation increases, atmospheric pressure decreases. This is due to the amount of air on top of you at your current elevation. At lower elevations, you have more air above you, and thus more pressure.
Do Fires destroy the ozone layer?
Wildfires have been found to cause the formation of ozone. Ozone in the upper atmosphere is useful, as it protects against certain harmful types of UV radiation. Wildfires have been found to cause ozone levels to rise at ground level, which is undesirable. Wildfires, however, do not impact the ozone layer.
Can humans survive without the ozone layer?
Life couldn’t exist without this protective ozone, which is also called the “ozone layer.” The sun gives off light, heat, and other types of radiation. Too much UV (ultraviolet) radiation can cause skin cancer, cataracts, and harm plants and animals.
Would Earth freeze without the ozone layer?
The Sun’s UV radiation is absorbed by the ozone layer. Ozone consists of oxygen atoms bonded in threes (O3); we breathe oxygen that’s bonded in pairs, or O2. Ozone forms in the mid-stratosphere. Without the ozone layer, the Earth’s surface would be sterilized by UV radiation.
Is there a hole in the ozone layer above Australia?
Firstly, the ozone layer in the mid-latitude (e.g. over Australia) is thinned, leading to more UV radiation reaching the earth. Secondly, the ozone layer over the Antarctic, and to a lesser extent the Arctic, is dramatically thinned in spring, leading to an ‘ozone hole’.
Why is there a hole in the ozone layer in Australia?
The stratospheric ozone layer absorbs the biologically damaging wavelengths of ultraviolet (UV) rays but in the 1970s, Australia’s ozone layer was severely thinned as a consequence of heavy use of ozone-depleting, substances such as chloroflurocarbons (CFCs) and hydro-chloroflurocarbons (HCFCs).
Why is the ozone layer thinner in New Zealand?
The ozone layer over New Zealand is thickest during spring and thinnest during autumn. The increase in UV transmission caused by the thinning of the ozone layer during summer is compounded by the sun being more directly overhead, so that UV has a shorter path through the atmosphere.
How does the ozone layer protect us?
The ozone layer is a natural layer of gas in the upper atmosphere that protects humans and other living things from harmful ultraviolet (UV) radiation from the sun. The ozone layer filters out most of the sun’s harmful UV radiation and is therefore crucial to life on Earth.
